Michonne tells Rick about the Governor once she enters the prison, while Merle confronts Glenn in Woodbury.

Rick and his group welcome another person to the prison in the next episode of "The Walking Dead". After escaping Woodbury, Michonne arrives at the prison, but she is forced to slay some zombies before being allowed to enter the building.

Once she's inside the prison, Michonne tells Rick and the other survivors about the Governor, who holds Glenn and Maggie hostage. The lovebirds are placed in separate rooms, with Glenn being interrogated by Merle who's seemingly still upset that he was left behind by the group in Atlanta.

"When the Dead Come Knocking" will air Sunday, November 25 at 9/8c on AMC.

Executive producer and "Walking Dead" comic book writer Robert Kirkman promises there will be more "awesome" things now that Rick's group and the Governor's group start meeting each other. "And I think that now that you've got Glenn and Maggie in Merle's hands and then you've got Michonne in the prison, things are going to start ramping up and we're going to start seeing these two groups clash. So look out for that kind of awesome," he gushes.
